The steam gasified the coal/char significantly at temperatures > 800 °C, leading to much lower char yields. Inorganic species in the coal/char also appeared to play an important role in such insitu steam gasification. In the droptube reactor, where the interaction time was much shorter, a noticeable effect on the char yield was only observed

Coal gasification technologies exist both for underground gasification and over ground gasification of coal. Technologies for over ground gasification of coal are of interest for production of DRI in shaft furnaces. It is well known that full combustion of coal does not produce the combination of CO (carbon mono oxide) and H2 (hydrogen)which is mainly desired in syngas for its further use as

The molten catalytic gasification process for converting coal into a synthesis fuel occurs at temperatures exceeding 700°C and results in syngas consisting of approximately 20 percent methane and 80 percent hydrogen. The molten catalytic gasifier process represents a way of converting coal or municipal solid wastes into a syngas with the potential to generate synthetic natural gas or

Clearly in order for coal gasification to happen any time soon the capital cost has to go way down, and that''s where in situ gasification comes in. Here what you''re doing is eliminating both the mining operation and the gasifier, two of the most capital intensive aspects of process. Instead you drill wells into a coal seam, initiate the gasification process with a burner and possibly steam and

Underground coal gasification (UCG) is a process by which coal is converted to useful gases in situ without the need for mining. The gases can subsequently be used to produce heat, generate power or synthesize a variety of chemical products. UCG is realized through circulating gasification agents (air or oxygen and water) into a coal seam.

The ISCG process uses injection and production wells drilled from the surface to access the coal seam and facilitate the process insitu. The coal is not extracted to the surface as there is no coal mine or coal handling facilities with ISCG. Through a high pressure gasification process, the coal is efficiently converted inplace in its original seam into synthetic gas. The synthetic gas is
